After transfection for 72 h, the total protein of cells lysed with RIPA lysis buffer (Beyotime, China) was determined by the BCA detection kit (Beyotime). Next, protein (30 µg) was isolated via 10% SDS-PAGE and transferred to PVDF membrane (Millipore, USA), and then blocked with 5% skimmed milk at 25 °C for 2 h. After removal, membranes were incubated with primary antibody: anti-p53 (ab241566; Abcam), p-STAT3 (ab76351; Abcam), STAT3 (ab68153; Abcam), p-JAK2 (ab32101; Abcam), JAK2 (ab39636; Abcam), GAPDH (ab8245; Abcam) at 4 °C overnight. After washing, the membrane was incubated with HRP-labeled secondary antibody 25 °C for 1 h, and then the signal strength of the proteins was analyzed using the ECL detection system (Millipore, USA) and Quantity One software (Bio-Rad, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
